AI-designed mRNA vaccine shrinks dog's cancer, fueling hopes for human treatment

An AI-assisted effort led to an mRNA vaccine that halved a dog’s mast cell tumor during a Sydney trial. The owner used a chatbot to brainstorm therapies and then worked with UNSW scientists who DNA-sequenced the tumor to tailor the vaccine. While the result is promising for pets and could inform human cancer research, experts caution against hype and note that more evidence is needed before any broader claims.
